FENCEMAKlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 321,359, dated June 30,1885.

Application filed April 23, 1884. (No model.)

To all whom it may concern:

Be it known that 1, Josnrn; M. HARROP, a citizen of the United States,residing at Quincy, in the county of Adams and State of Illinois, haveinvented certain new and useful Improvements in Fence-Making Machines;and'I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a side elevation of myinvention. Fig. 2 is a longitudinal horizontal sectional view, and Fig.3 is a plan view. Fig. 4 is avertical transverse sectional view. Fig. 5is a detail view of the clamping device, and Fig. 6 is a detailsectional view of one of the rack-bars and guideways attached to theframe A. Fig. 7 is a vertical sectional view of the middle portion of mymachine, showing a picket in a position to enter between thebinding-wires, and two of the pickets strung.

This invention has relation to improvements in machines for makingpicket or slatted fences; and it consists in the construction and novelarrangement of devices, as will be hereinafter more fully set forth, andparticularly pointed out in the claims appended.

In the accompanying drawings, A indicates the frame of the machine,which is of a suitable height, and properly braced to support thefencing and mechanism for forming the same. Atthe rear end of the frameare two rows of double spools carrying the slat-binding wires. Thesespools are loosely supported and allowed to freely rotate on shortlateral or transverse shafts,which are secured to longitudinal hollowshafts b, and extend at right angles therefrom. These shafts b havetheir opposite ends supported, respectively, in the rear vertical beam,L, of the main frame, and an intermediate vertical beam, K, which isalso secured to the main frame, as shown.

The upper and lower longitudinal beams of the frame A are provided ontheir inner sides with fixed guide-plates a and sliding in these guideplates are longitudinal rack-bars 13,

near the forward ends of which is secured a vertical bar, O. Journaledto the outer side, and about midway the length of this bar O, is avertical bevel-gear, (2, having its fixed shaft provided with anoperating-crank, D, and to the opposite side of the said bar 0 arejournalbearings for supporting the twisting-forks B, the said forksbeing allowed to rotate freely in the bearings. The twisting-forks arerespectively provided with fixed vertically-arranged intermeshinggear-Wheels e, and the central fork-shaft has a rearward extension, I,which is designed to enter the central hollow shaft, 1), supporting thespools. On this shaft P, which is also fixed to the'bevelgear d, isarranged a spiral spring, in, having one end fixed to the said shaft b,and the opposite end fixed to the bevel-gear d, which has an engagementwith the bevel-gear c. The horizontal shafts b are respectively providednear their rear ends with intermeshing gear-wheels b, which are fixedthereto. Thus it will be seen that when power is applied to the crank D,which turns the bevel-gear a, motion will be simultaneously communicatedto the twistingforks by the engaging bevelgea-r (Z and the intermeshinggears e, and to the central shaft, I), through the medium of the spiralspring we, and gear cl,when the motion thus attained will be imparted tothe respective shafts I) by the fixed gears 12.

F indicates a vertical rock-shaft having its bearings in the main frame,and extended a sufficient distance above the same for the attachment ofthe picket-feeding arms, as will be presently explained. This shaft F isprovided with two horizontally-fixed pinions, f, which are designed toengage the rack-bars, respectively, and move the same back and forthwhen the said shaft is operated. F indicates the operating-arm of thesaid rockshaft. The forward ends of these moving racks B are providedwith branched extensions Z, which have curvilinear slots to, and areconnected with a transverse bar, V. The outer ends of this transversehorizontallymoving bar are pivotally connected,by means of links a, withthe ends of the laterallymoving vertical clamping-bars R.

The clamping bars It are supported by transverse rods T, which aresecured at oppoforks, or where the site ends to the main frame, so as toallow the said clamping-bars a sliding transverse movement when theracks B are operated. The clamping-bars R are also provided in theiradjacent edges with notches or projections s, for passing over thebinding-wires, while the said clamps are brought against a picket during the twisting operation of the forks.

I indicates a winding-drum at the forward end of the frame, for rollingup the fencing as it leaves the machine. This drum is provided at oneend with a fixed ratchet or toothed wheel, H, and a radial arm, 9,carrying a pawl for engaging the ratchet-wheel, and the outer end ofthis arm 9 is connected to the vertical rock-shaft F by means of a rod,G, and an arm, J, fixed to the said rock-shaft. Therefore, when theshaft F is rocked to feed the pickets and operate the clamping-bars, thefencing as it is formed is simultaneously wound upon the drum. Theshafts b are hollow and provided with apertures for the passage of thewire from the spools to the forks.

J indicates a tension-roller, which is vertically journaled in the mainframe in advance of the twisting-forks.

Upon the main frame and above the clampi ng and twisting devices isarranged thepicketholding device, which consists of a verticaltransverse guideway, L, within which are vertically arranged thepickets. The floor of this guideway is provided, directly above thebranches of the twisting-forks,with a vertical elongated slot, M,through which the pickets are dropped so as to fall between thebindingwires as they leave the forks.

A indicates longitudinallyvibrating arms, which are eccentricallyclipped to the vertical rock-shaft F, as shown at D. These arms A extendtransversely across the slot M of the picket-guideway, and areshouldered,as shown at (L so as to receive the pickets as they are fedby any suitable means in the guideway and carry them to the said slot.The slot M is of a size sufficient to receive but one picket at a time,and the shoulders of the arms A are also constructed so as to engage butone picket. Therefore it will be seen that as the rock- 'shaft isoperated the said arms engage and carry the pickets to the slots, wherethey are dropped slightly in advance of the forks and between thebinding-wires.

It will be perceived that the spools carrying the binding-wires have arotary movement similar to that of the forks, the object being toprevent the wires from twisting after leaving the spools at any pointother than at the pickets are dropped or bound.

The operator stands with one hand upon the lever F of the verticalrock-shaft, and the other upon the crank-arm D of the gear 0, the lcverFbeing directed forwardly or toward the winding-drum, and the forks lyingin the opposite direction, with the branches of each respective fork onthe same horizontal plane.

The operator then moves the lever F rearwardly or in the directionindicated by the Q arrow in Fig. 1. This causes the arms A A to engageand carry a picket to the slot M; the forks to go forward so as to havethe space between their branches to coincide with a vertical line fromthe said slot M; the clamps R to separate for the introduction of thetwisting-forks and the picket which drops between the branches of theforks and clamps, respectively. The same movement, through the medium ofthe rod G and its connections with the shaft F and drum I, causes thepawl on the said rod to engage the teeth on the wheel Hand turn the drumI, fixed thereto. A picket being new between the loops of the respectivewires, the operator moves the lever F in the opposite direction, causinga reverse movement of the devices before mentioned, and the said pawl toride over the teeth on the wheel H and engage them at the desired point,and the clamps R to engage the picket. He then turns the crank-arm D inthe direction indicated by the arrow, when the forks, through the mediumof the gears G and d and gears 6, will be rotated, thereby twisting thewires around the picket, the spools at the same time being given asimilar movement to the forks by the gears 22, receiving motion from thecentral shaft, 12, imparted to it by the spring at on the shaft P, whichhas one end fixed to the gear d, and the opposite end attached to thesaid middle or central shaft, b. means may be employed for holdingthepicket in a vertical position during the withdrawal of the forkstherefrom and the approach of the clamps; or the operator may, ifdesired, hold it in such position by his hand.

Having described this invention, what I claim is 1. The combination, inafence-machine, of the twisting-forks, their gear-wheels, the movingracks, and means for operating the same, substantially as specified.

2. The combination, with the movable bar carrying the twisting-forks,the rack-bars, the rock-shaft carrying the pinions, means for rotatingthe winding-drum, and means for connecting the rock-shaft with thewindingdrum, substantially as specified.

3. The combination, with the movable bar carrying the twisting-forks, ofthe rack-bars, the clamping device, and means for reciprocating androtating the twisting-forks, and for operating the clamps, substantiallyas specified.

4. The combination, with the rack-bars having branch extensions, thetransverse rodsforming slides for the clamping-bars,the transverse barsconnected with the branches of the rack-bars, and the links connectingthe clamping-bars with said transverse bars, substantially as specified.

5. The combination,with the twisting-forks and their supporting movablebar, of the racks, bevel-gears c and d, and means for par- Any suitableICC tially rotating the spools carrying the bindingwires, substantiallyas specified.

8. The combination, with the main frame, of the picket-guide troughhaving the vertical slot, the rock-shaft, and the vibrating arms securedto the shaft for feeding forward and dropping the pickets to thetwisting devices, substantially as specified.

In testimony whereof I affix my sign ature in presence of two witnesses.

JOSEPH M. HARROP.
